[FIX] stock-account: UserError on div by zero

With:
- Anglo-saxon activated,
- Costing Method: FIFO,
- Inventory Valuation: Automated.

Create a PO for product AAA, receive the product and archive it,
create and try to POST the vendor bill.
> This lead to a ZeroDivisionError: float division by zero

The anglo-saxon entries cannot be generated as the product
is not valued anymore.

This commit is displaying a clearer error message for end users.
